10 Worst Bets in a Sportsbook: Avoid These Mistakes
Betting is exciting, but to truly win, avoiding common pitfalls is crucial. Many bettors unknowingly make choices that heavily favor the house. This guide highlights the 10 worst bets you can place in a sportsbook. Read on to improve your betting strategy and gain the edge.

1. Double Chance Bets
Double chance bets may appear safe, but sportsbooks inflate the house edge here. Let’s break it down:
Example: Leicester vs. Chelsea odds – 4.75 (Leicester), 4.33 (Draw), 1.63 (Chelsea). The double chance (1X) is offered at 2.20.
Calculation shows placing two separate bets (Leicester and Draw) yields better odds of 2.27.
Why avoid? Sportsbooks bank on punters skipping the math, meaning you often settle for worse returns.
2. European (3-Way) Handicap

The European handicap disguises a higher house edge.
Example: Odds of 4.75 – 4.33 – 1.63 carry a 5.3% house edge. In a 3-way handicap, odds of 2.20 – 3.70 – 2.45 increase the edge to 11.73%.
Why avoid? The jump from a 5.3% to 11.73% house edge doubles the sportsbook’s cut.
3. Bet Builders

Bet builders combine multiple legs (e.g., a player to score, number of corners, team to win) into one wager. While marketed with “odds boosts,” they often hold a 30-40% house edge.
Why avoid? Bet builders exploit bettors’ lack of ability to calculate contingent probabilities, making them profitable for sportsbooks but bad value for you.
4. Parlays (Accumulators)

Parlays multiply the house edge across bets.
Example: A single bet with a 5% house edge is manageable. In a 3-leg parlay, the edge compounds, and a 10-leg parlay pays far below true odds.
Why avoid? Small individual house edges become massive multipliers in parlays. Betting 25-30 team parlays gives worse odds than a lottery.
5. Each-Way Bets

Common in horse racing, each-way bets combine win and place bets. Most follow “standard terms” (e.g., 1/5th odds for a place), which heavily favor the house.
Example: In a 10-horse race, win bets carry a 17.65% over-round. Place bets inflate this to 33.33%.
Why avoid? Unless using advanced methods like “each-way thieving,” standard each-way terms are poor value.
6. Cashout Options

Cashouts allow bettors to settle bets early at reduced returns.
Example: In a 6-leg parlay where five legs hit, a $20 bet with $251.37 potential payout might offer $225 to cash out, costing you $26.37.
Why avoid? Cashouts often result in giving back around 10% of your ticket’s actual value.
7. Betting on Something to Happen

Sportsbooks frequently offer odds on events (e.g., “Team A to score 3 goals”) without an option to bet against them.
Why avoid? If you can’t bet on the opposite outcome, it’s likely the odds hold an inflated house edge.
8. Betting After Odds Drop

Sharp bettors know timing is everything. Odds that drop often mean value is gone.
Example: A tipster releases a 25/1 pick, and sportsbooks slash odds before taking bets. Betting at lower odds usually isn’t profitable.
Why avoid? Betting without value is a losing strategy, as pro betting revolves around odds, not teams or players.
9. Futures (Ante Post)

Futures markets often carry massive house edges, especially in long-term bets like season outcomes or tournament winners.
Example: Before a season, top football leagues show a 140% over-round. Ante post horse racing odds can exceed 200%.
Why avoid? Tying money up in futures bets with massive over-rounds diminishes long-term profitability.
10. Bonus Bets

Free bets or bet credits can be useful but come with caveats.
Example: A $1,000 bonus bet at odds of 1.27 returns $207 expected value, while betting at higher odds (e.g., 3.90) yields $682 expected value.
Why avoid? Misusing bonus bets by chasing low odds reduces their true value.
